Application filed September 4, 1915. Serial No. 48,944.

a citizen of the United States, residing at Peoria, in the county ofPeoria and State of Illinois, iave invented certain new andusefulImprovements in Elevators, of which the following is a specification.

My invention relates to elevators, and has special reference to anelevator used in conjunction with a threshing machine or separator.

The object of my invention is to provide supplementary means to theordinary auger used in connection with the cross conveyor of aseparator, in aid of the feeding of grain into the boot of the elevator.

My invention lies in the provision of deflector members in conjunctionwith belt carrying wheels for conveyor members of an elevator, to talrethe place of ordinary spoke members ofsuch wheels.

My invention also includes the relative ar-' rangement of the deflectormembers of each of said belt wheels to cause opposite deflection, thatis, that each may deflect grain toward the vertical center of the bootof the elevator.

My invention also comprehends detail arrangement and formation of partsauxiliary to and in aid of results sought to be obtained.

Referring to the drawings l igure 1 is a side elevation of the lowerportion of an elevator; 2 is a front view of the lower section of anelevator with parts broken away to show interior construction andarrangement parts, and also showing in section a portion of thestructure of a sepa- "rator including an auger conveyor and theconnection between the auger conveyor or housing, and the boot of theelevator; Fig. 3 is a detail front elevation of the belt wheel andinclud'ng a showing of the manner of fixing the same upon a shaftyFig. 4is sectional view on the line o-o of Fig. 3; Fig. 5 is a sectional viewon the line 6-?) of Fig. 3; Fig. 6 is a detail perspective view of abelt wheel.

I have had an extended experience in the manufacture of grain weigherattachments for threshing machines, such attachments including anelevator adapted to receive the discharge from a thresher. In theorganization or arrangement of the auger feed and the elevator, it isnecessary to extend the conveying elements of the elevator to a pointclose to the bottom of the boot portion and the necessary belt carryingwheel members are therefore required to be dis posed in the line ofdischarge within the elevator boot. I have learned from my experiencethat the ordinary spoke members of the wheels or the wheel adjacent thereceiving inlet of the boot, very materially interfere with the entranceof grain when the wheel is in rapid motion. As a result of suchexperience, and, in some grain sections, the failure of elevators tomeet requirements as to capacity, I was led of necessity to eitherenlarge the elevator or find means for increasing the feed to theelevator boot. This led to my present invention, which involvessubstitution of deflector members for the ordinary spoke members, suchdeflect members being formed substantially in the shape of auger blades,and the wheels containing such members being disposed in the line oftravel of the grain act to deflect it and convey it instead ofobstructing its passage, as in the instance of ordinary spoke members.

To facilitate the positioning of the elevator at either side of themachine in accordance with the provided means of discharge in connectionwith different makes of separators, I have provided similar wheels, withsimilar deflector or auger blade members, in connection with both beltcarrying wheels, but reversing the position or bearing of the blademembers to accommodate the difference in the direction of the discharge.lo both instances of application, the feed is toward the vertical centerof the boot of the elevator. Also, the provision of oppositely bearingdeflector members in connection with the two belt supporting wheels produces a l'JGIlGfiClELl result in that the OPPOSWQ extension from troughmember the ordinary hopper member of a separator; 3 to an auger troughdisposed below the hopper; a to an auger shaft and 5 to the ordinary andusual auger member.

6 is a partially truncated conical member 7 is a hanger in said memberadapted to support one end of the auger shaft.

8 is a truncated conical shaped cast member adapted to be bolted orproperly secured to the side of boot member 9 of the elevator and aboutthe entrance opening 10 into said boot. 11 is a cap or closure memherfor an opening on the opposite side of boot similar to opening 10, saidcap being applied interchangeably to one side or the other of theelevator boot, according as the elevator may be placed on one side ofthe separator or the other.

12 are the ordinary lug members of an elevator.

13 are the ordinary bucket or conveyer belts provided with bucketmembers l l secured at intervals of its length. Belt 13 is adapted to besupported in the usual manner in the upper or head portion of theelevatorbody and to be driven from such support. I

15 are wheels about which belt members 13 are adapted to travel at thelower reach of the conveying element, said wheels being fixed to shaft16 by means of set screw 17. Shaft 16 is supported in sleeve member 18,the same being spaced between the hub members of wheels 15. Sleeve 18 isintegrally or otherwise securely connected with bracket member 19, theupper end of which said bracket member is fixed to the elevator framingin position to properly dispose wheel members 15 for proper workingrelation.

Referring now particularly to wheel members 15, it will be noted that Ihave provided deflector or'auger members 20, said members beingcomparatively thin and extending substantially the full width of saidwheels, and such deflector auger members have opposite bearing orinclination respectively in the two wheel members. The deflector augermembers 20 having an angular disposition with relation to the axis ofwheels 15 and being flush with such face, has the eifect to pre sent arather sharp or cutting edge in the direction of travel of said wheelsso that as the wheels are revolved the rear sharp edge of the augermembers of said wheels are presented to the grain and produce the leastpossible friction or deflecting tendency, then, as the grain passes theedge and meets the gradually tapering surface of the blade members, therevolution of the wheel serves to force or deflect the grain toward theinterior of the boot member. Similarly, as the grain is forced throughthe wheel on the entrance side of the elevator boot and to the oppositeside of said boot, and in contact with the oppositely disposed wheel,any banking upon said opposite side will be prevented by the action ofthe deflector or auger members of said wheel, the same acting to deflectthe grain back toward the interior of the boot.

In operation, the parts being positioned relatively as disclosed in thedrawings, with the wheel member 15 disposed as it necessarily must be,within the area of the inlet or opening 10 into the boot member of theelevator, the grain separator auger acts to force the grain into theelevator boot, under some conditions of flow from the separator, part ofit, when the auger trough runs full, passing below the wheel member 15and part through the wheel member 15, the deflector auger blade membersof said wheel serving, as hereinbefore deseribed,to present a carryingand deflecting surface, which greatly facilitates the travel of grainthrough the wheel. The conveyer elements of the elevator act and operatein the same manner as they do generally in elevators of this character.i

I have shown herein two deflector members in the belt supporting wheelmembers of the conveying element of the elevator. However, I do not wishto confine myself to any particular number of such deflector members,but wish to employ any number that maybe found efficient in practicaluse.
